Abstract: During a scan line driving phase, a column driver is controlled to provide a plurality of driving column voltages to the source terminals and the row driver is controlled to provide scanning row selection voltages to the gate terminals for sequentially updating the each pixel having an initial pixel state, voltages with said plurality of driving column voltages to attain, for each initial pixel state (600), an initial common pixel state (608). During a common driving phase the column driver is controlled to provide a uniform column voltage to the source terminals. This voltage is used for updating the plurality of pixel voltages with a uniform column voltage. In addition, the row driver is controlled to provide row select voltages with a gate swing that is lower during the common driving phase than during the row driving phase so as to drive the pixels from a respective the initial common state to a respective final common state. The pixel states may differ from each other at least during a part of the common driving phase or even during the entire common driving phase, so that initial and final common states and intermediate states may differ from pixel to pixel.

Abstract: An image is updated on a bi-stable display (310) such as an electrophoretic display in a transition from a current image state to a subsequent image state. A voltage waveform (600, 620, 640, 660; 700, 720, 740, 760) is selected based on the current and subsequent image states, and a previous image state. The bi-stable display (310) is driven from the current image state to the subsequent image state using the selected voltage waveform. For a given transition from the current to the next image state, different waveforms are stored for different previous states, e.g., black, dark grey, light grey and white. The different waveforms may have different drive pulse (DR) or reset pulse (RE1, RE2) energies. In a trial and error optimization process, different waveforms with different reset and/or drive pulse energies are tested for different previous image states to see which waveform yields the smallest greyscale error.

Abstract: Display units (1) comprising pixels arranged in rows and columns coupled via transistors (12) to row (41, 45, 49) and column (31, 32, 39) electrodes show a relatively large gradient in the image. By introducing means (30, 40) for reducing a voltage difference resulting from a voltage jump on a predefined line, which voltage jump arrives via a capacitance (13, 14), this gradient is reduced. The capacitance (13, 14) may comprise a storage capacitor (13), with the predefined line being a neighbouring row electrode (41, 45, 49) or a separate storage line (25). The capacitance (13, 14) may also comprise a parasitic capacitor (14) of the transistor (12), with the predefined line corresponding with the row electrode (41, 45, 49) in the same row. The means (30, 40) comprise line driving circuitry (40) and data driving circuitry (30) for supplying a data signal to pixels (11). The means (30, 40) may also comprise line driving circuitry (40) for driving at a reduced amplitude and may comprise storage line driving circuitry for driving the storage line (25).

Abstract: Display units (1) comprise display panels (90) which are divided into active parts and inactive parts. The driving of an entire display panel (90) requires a minimum amount of time, which amount of time increases with an increasing number of rows and columns. By providing data signals to the pixels (11) located in active parts, and by supplying reference signals simultaneously to pixels (11) located outside the active parts, most of an amount of time available in a frame period is used for the active part, and, for a given frame period, the number of rows and columns of the display panel (90) can be increased. Respective parts are made active during respective frame periods. A part may comprise a group of columns (ADG, BEH,CFI) and/or a group of rows (ABC,DEF,GHI). The display panel (90) may comprise multiplexing circuitry (50) and/or shift register circuitry (60) to reduce the number of connections between the display panel (90) and the rest of the display unit (1).
